Specification of Letters Patent.

Patented Oct. 27, 1908.

Application led May 24, 1907. Serial No. 375,515.

To all whom it may concern:

Be it known that I, HUGO SCHUBERT, a citizen of the United States, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Ovens, of which the following is a full, clear, and exact description.

This invention relates more particularly to a bakers oven.

The primary object of the invention is to provide simple and efficient means whereby an oven is rovided in which the heat is evenly distrlbuted, and in which the oven may be qliilickl cooled, or have its temperaturel quic y c anged to adapt it for baking various kinds and classes of articles.

A further object of the invention is to pro vide means whereby the greatest efiiciency is obtained by causing the products of combustion to circulate properly around and about the oven before passing to the chim- FVith these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be polnted out in t e claims at the end of the description.

In the drawings, Figure 1 is a vertical section of one form of oven embodyin my invention, taken on the line I-I o Fig. 2. Fig. 2 is a sectional plan taken on the line IIII of Fig. 1. Fig. 3 is a sectional plan through the oven taken on the line III- III of Fig. 1. Fig. 4 is a sectional plan taken on the line IV-IV of Fig. 1. F1g. 5 shows a slightly different way of su porting the beams of the air chamber; and Fig. 6 is a sectional plan taken on the line VIwVI of Fig. l

The oven is ordinarily constructed of brick or a combination of brick and other material, and may be of any desired sha e. As shown the settlng or casing 10 is provi ed with a suitable rate 11 over which is an arch 12 forming te usual furnace or furnace chamber. The furnace chamber has longitudinally extending side partitions 13, and in said partitions are openings 14 near the front part thereof through `which ass the roducts of combustion to each si e of the urnace to the chambers 15. These chambers have a side wall, deflector or partition 16, and at the rear of each of said partitions are openings 17 which form a communication between the chambers 15 and the chambers 18. One or more flues 19 are arranged at the rear of the furnace through which some of the products of combustion pass, and at the front portion of the chamber 18 are the iiues 20, shown in dotted lines Fig. 2 and full lines Fig. 8, through which most of the products of combustion from the furnace pass after passing through the chambers 15 and 18, and from there pass into the heating chamber 21 arranged over. the oven proper or baking chamber 22. By this means the products of combustion are made to take a circuitous route through the various chambers before passing into the heating chamber 21.

An air chamber 23 is arranged beneath the oven or baking chamber 22, and over the furnace and the chambers 15 and 18. The chambers 15 and 18 each have an arch of brick or other material, and said air chamber 23 is formed by a series of arches which rest upon the flange of the I-beams 24. These I- beams 24 are set in concrete 25, and over the concrete is a la er of sand 26, and above the sand are the ti es 27 forming the base of the oven proper 22, though instead of the I- beams being supported as shown, the partitions 13 of the furnace may be extended so ihat the beams will rest thereon as shown in The upper part of the oven or baking chamber 22 is arched, as at 28, and forms the lower surface of the heating chamber 21. This chamber 21 has a series of partitions or deiiectors as best shown in Figs. 1 and 4 to cause the products of combustion to pass alternately from front to rear of said chamber so that the latter will be evenly heated throughout its entire surface. The products of combustion from the lues 20 pass upward on the outside of thevoven 22 and enter the chamber 21 at the front ends thereof. This chamber 21 is provided with: a plurality of deflectors or partitions 29, each of which has an opening 30 which alternate with respect to each other, so as to cause the products of combustion to pass from the front to the rear and then to the front again and so on to the central part thereof. At this point there is a partition 30a, forming independent compartments, and on each side of the partition at the front thereof is a Hue 31 in each of which is arranged a damper 32. The dampers 32 are arranged to control the exit of the products of combustion from the chamber 21 so as to regulate its passage to the chimney iiue 33, which may be located at any convenient point so as to connect with the usual chimney. The flues 19 at the rear open into the central chambers 34 and 35, by which a part of the products of combustion may pass direct to the chimney ilue 33. By closing either of the dampers 32, the oven or baking chamber 22 may be heated on one side only, or throughout its entire surface as desired.

For the purpose of cooling the baking chamber so as to obtain quickly different degrees of temperature to adapt the oven to bake different articles requiring different degrees of heat, I arrange at the rear of the baking chamber one or more iiues 36. These flues 36 may be of any suitable shape and may b'e located at any desired point, and said flues may connect in any suitable way with the chimney flue and are each provided with a 'damper 37 by which the said flues may be opened or closed as desired. These dampers are provided with a rod which may be operated from the front of the oven setting so that by opening said dampers the baking chamber may be quickly cooled, Vand by closing the same the heat may be properly retained within the chamber.

It will be understood that where the heat comes in contact with the setting, the same may be lined with fire-brick for the purpose of making the oven and parts more lasting, and 'it will be further understood that the eX- act arrangement and the position of the partitions and flues may be changed without departing from the character of the invention.

From the foregoing it will be seen that simple and eiiicient means are provided whereby the heat from the 'furnace may be caused to pass throughout the entire length and'width of the baking chamber, and from there is caused to pass by a circuitous route over lthe entire upper surface'o'fsaid chamber before passing to the chimney iiue, and that said baking chamber may have its temperature regulated to eXactness and may have its temperature changed 'for the purpose of .per- Initting various articles to be baked therein.

Having thus described my invention, l claim as new and desire to secure by Letters Patent 1. In a bakers oven, the combination with a setting havinga furnace chamber, of an air chamber over the furnace chamber, a heating chamber having independent compartments separated by a central partition, a baking chamber between the air chamber and the heating chamber, chambers arranged along the furnace chamber at the side thereof, a plurality of partitions arranged in the heating chamber on each side of the longitudinal center and having openings arranged alternately so as to cause the heat to pass from the front to the rear yand vice versa, a plurality of iiues leading from the baking chamber to cool the same at each side of the longitudinal vcenter thereof, means for controlling each oven flue independent of the other, iiues connecting the chambers at the side of the furnace chamber and the heating chamber, and flues connecting the furnace chamber with the heating chamber at the front and rear thereof, whereby the products of combustion is made to pass to the front and to the rear of the heating chamber to distribute the heating evenly over the baking chamber.
